This is bad even for a mobile port. Note that the two buttons on the right have flame-effects and there's REALLY LOUD MUSIC playing:

The gameplay itself is quite interesting and unusual. It's a CCG with 4 lanes. Each lane contains a champion which comes with its own set of rules. Each champion has a "quest" - if you perform 4 specific actions in turn you get a special super-card (blessing). It's all quite clever but they fail to explain even basic elements (like certain quest icons). It mostly reminds me of Gwent, which also had limited draws and no combat between units.

I've never heard of PlayFusion but they have to be Japanese-Norwegian because they're all about catching whales. The "loot" section (where your earned booster packs and the like go) falsely implies you have loot while it's really a "daily card" you can only buy with gems. The store is loaded with ""deals"" and every time you open it it shows the same popup about all the "great" rewards you get with your first gem purchase. Oh, and there's a subscription model too! And physical cards you can scan into the game! Wow.

Perhaps worst of all is how apparently they have Space Marines in non-40K Warhammer too now. Ugh.
